We are a part of universe. Biggest part known to science is system of infinite galaxies. In one of the galaxies there is our planetary system. If we further move in then we have our beautiful planet Earth, Seven continents, and 6.4billians human beings living on plates. In average, about 400 people have been outside the Earth's atmosphere each year, and, of these, may be twelve have walked on the Moon. Normally the only humans in space are those on the International Space Station.
Now imagine a chance that you meet a person or more who are just like you out of known 6.4 Billion population of this Universe. May be they are same entity as you and you never know unless you meet them. He/she may be a single person in the whole universe or may be 7 or 8 or 10 but you never know. More chances are there they may be up to 7 not more than that. Assuming each big sector plate contain one alike you.
All depends upon the natural equations and the solution of that equation. Yes, all we have a certain equation which we are following and our life goes on that pattern which is in rhyme with our surroundings, situations and each front of life. It is all control by that single equation in which you are putting your input daily, each second you are living, that patterns flows spontaneously and show you a solution which you see as your life.
But, there are chances that some people in the universe are living his/her life in the same pattern as you. How many people you meet daily?, and you could never meet the life who is almost same as you, because you are controlled by that big equation which results in a pattern and that makes you blind folded to see only a part of it which you feel as a guaranteed life . Have you ever imagine life beyond than that which is visible to you accessible to you. Do you feel that there is some life you never can imagine? Because if you imagine something that becomes part of you, that becomes accessible. Now think if there is something we never thought of and suddenly comes in front of us what name we will give to it?, an incident, an event, a person, a chance, a new life, and we accept it as it is. Have you ever met the life alike you?
